WET GAS-METER.

SPECIFICATION forming part of Letters Patent No. 268,251, dated November 28, 1882.l Application ledJuly 22, 1882. (No model.)

To all whom tt may concern.-

Be it known that I, WILLIAM MAcKIN'rosH, of Callao, Peru, South America, have invented certain new and useful Improvements in Wet Gas-Meters, oi' which the following is a full, clear, and exact description.

My invention consists in certain novel features of construction of wet gas-meters, having the object to secure correct and `unvaryin g measurement of'the gas at all times without regardto the change in the water-level, and also to furnish a meter that shall not require to be charged with water except at long intervals.

Reference is to be had to the accompanying drawings, forming part of this specitication, in which similar letters of reference indicate corresponding parts in all the figures. f,

Figure l is a frontvieugwith the face of the breast removed, showing in dotted lines the oat and drum in an elevated position. Fig. 2 is a vertical section through the outer casin g of the meter, showing the float and drum in their lower position. the meter, partly sectional. Fig. tis a horizontal section. Fig. 5 is a detail section, showing theoutlet-coupling and the device for securing the float and drum against movement.

A is the outer casing ot' the meter containing the oatB, which carries or supports the measuring-drum C.

D D are bearers fitted across the float for supporting axis r of the drum.

E is a worm upon the end of the shaft of the measuring-drum.

F is a long worm-wheel or toothed cylinder, sustained on a shaft by suitable bearings in the breast n, and engaging the worm E.

Fig. 3 is a side view of4 e is a water-funnel, provided with tube f for filling the meter. y

g is the tube, containing the spindle ot' the worm-wheel F.

m is the box, containing'the index mechanism, Withwhich the wormwheel Fis connected.

p is a bent wire, fitted at oue end with a float, i, and formed at the other end as a gage, t, for indicating the height of water, and also carrying above the float t' a stopvalve,j, which, when the iioat is in its lowest position, closes the gas-inlet.

0 is a trap or casing immediately surrounding the worm-wheel F and worm E and opening Kin the division-plate, so as to prevent escape of gas through the opening K tothe measuring-drum without being registered, when the water is low.

s is the plug for adjusting the water-level.

tu t0 in Figs. 1 and 3 show the water-line at the highest point with the meter ready for operation, in which case, as will be seen, the worm E of the drum engages the upper end of the worm-wheel F. As the water-level falls the iioat B, moving downward, will carry the drumdownward, and the worm E will move down upon the worm-wheel F until it reaches the lowest point, as shown in Fig. 2, when the gas will be shut out of the meter by the valve j. By this construction the meter will register correctly in any position ci"` the iioat between the highest and lowest points. The extent" of this movement will vary according to the size of the meter, and in the smallest `size meters the evaporation required to move the float to its lowest point being considerable, the meter will operate for a long period of time without havingto be recharged with water.

To prevent any movement of the iioat and injury of the same during transportation, the screw Mis to be turned by a suitable key, inserted through the inlet-cone until the screw comes in contact with the bridge N, when in that case the oat will be held down upon the bottom of the meter, as in Fig. 2.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the measuringdrum C, having axis or shaft i', of the iloat B,

having cross-beams D D, whereby the drum is 4. The combination of the inlet-cone d, the

' supported by the float, as described. screw M, and the bridge N, whereby the screw 2. The dip oase or trap o, fitted around the may be operated, as and for the purpose worm-gearing F E, and covering the opening specified.
